AI Absolute Accuracy Equation
AbsoluteAccuracy = Reading · (GainError) + Range · (OffsetError) + NoiseUncertainty
GainError = ResidualAIGainError + GainTempco · (TempChangeFromLastInternalCal)
+ ReferenceTempco · (TempChangeFromLastExternalCal)
OffsetError = ResidualAIOffsetError + OffsetTempco ·
(TempChangeFromLastInternalCal) + INLError
NoiseUncertainty = Random Noise ⋅3
100 for a coverage factor of 3 σ and averaging
100 points.
AI Absolute Accuracy Example
Absolute accuracy at full scale on the analog input channels is determined using the following
assumptions:
• TempChangeFromLastExternalCal = 10 °C
• TempChangeFromLastInternalCal = 1 °C
• number_of_readings = 100
• CoverageFactor = 3 σ
For example, on the 10 V range, the absolute accuracy at full scale is as follows:
GainError = 60 ppm + 13 ppm · 1 + 1 ppm · 10 = 83 ppm
OffsetError = 20 ppm + 21 ppm · 1 + 60 ppm = 101 ppm
NoiseUncertainty = 280 µ� ⋅ 3
100 = 84 µV
AbsoluteAccuracy = 10 V · (GainError) + 10 V · (OffsetError) + NoiseUncertainty =
1,920 µV

Maximum Working Voltage
Maximum working voltage refers to the signal voltage plus the common-mode voltage.
Channel-to-earth 11 V, Measurement Category I
Measurement Category I is for measurements performed on circuits not directly connected to
the electrical distribution system referred to as MAINS voltage. MAINS is a hazardous live
electrical supply system that powers equipment. This category is for measurements of voltages
from specially protected secondary circuits. Such voltage measurements include signal levels,
special equipment, limited-energy parts of equipment, circuits powered by regulated low-
voltage sources, and electronics.
Caution Do not use for measurements within Categories II, III, or IV.
Note Measurement Categories CAT I and CAT O (Other) are equivalent. These test
and measurement circuits are not intended for direct connection to the MAINS
building installations of Measurement Categories CAT II, CAT III, or CAT IV.
